Essentials
At the start, go forward and turn right. Flip the switch to the right to raise stairs then open the door to the west. Ahead you see an intersection. Turn left and go straight to a room with computer terminals, then press the switch on the north side of this room. Return to the intersection and this time go to the west. You'll arrive at another room with computer terminals, use the switch on the south side of this room then enter the teleporter to your left. Collect both keys, then enter the northern teleporter from its west side. Go forward, then open the yellow and blue bars and enter the exit teleporter.

Secrets

 * 1) At the intersection near the start, go down the stairs to the south. To your right (west) is a door, so open it and enter the room with keys in a water pool. On the southern wall of this room is a lift. Lower it, and use it while facing east. As the lift goes up, you'll spot an alcove containing a plasma gun and a computer area map. (sector 44) If the lift raises while you are in the secret, press it again to lower it.
 * 2) In the room with computer terminals to the south, on the southern wall is a screen with static. Press this screen to raise it, revealing a small alcove with two boxes of shotgun shells and two boxes of rockets. (sector 121)
 * 3) In the water pool containing both keys, use the southern teleporter but don't move after being teleported. Instead, turn south and run forward to reach a water area. Move to the northeastern part of this area and press the misaligned wall to the west of the waterfall for a soulsphere. (sector 102)
